Simplify the following expression. cot^2x secx-cosx

Solnce55 [7]

ANSWER

$\cos(x) \cot ^{2} (x)$

EXPLANATION

The given expression is;

$\cot^{2} (x) \sec(x) - \cos(x)$

Change everything to

$\sin(x)$

and

$\cos(x)$

This implies that,

$\frac{ \cos^{2} (x) }{ \sin^{2} (x) } \times ( \frac{1}{ \cos(x) } )- \cos(x)$

Cancel the common factors,

$\frac{ \cos(x) }{ \sin^{2} (x) } \times ( \frac{1}{1} )- \cos(x)$

$\frac{ \cos(x) }{ \sin^{2} (x) }- \cos(x)$

$\frac{ \cos(x) - \sin ^{2} (x) \cos(x) }{ \sin^{2} (x) }$

$= \frac{ \cos(x)(1 - \sin ^{2} (x) ) }{ \sin^{2} (x) }$

$= \frac{ \cos(x)(\cos^{2} (x) ) }{ \sin^{2} (x) }$

$= \cos(x) \cot^{2} (x)$

Tickets for the school play sell for S4 each. Which graph shows the relationship between the number of tickets sold

Fiesta28 [93]

Answer:

Step-by-step explanation:

Tickets for the school play sell for $4 each.

Number of tickers sold = x

Total income from the tickets = y

This means when x = 1, y = 4

SO when we sell 1 ticket (x = 1), we make $4 income (y = 4).

If we sell 2 tickets (x = 2), we will make $8 income (y = 8)

If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)

If we sell 4 tickets ( x = 4), we will make $16 income ( y = 16) etc.

Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).

So if you create a graph, it should look something like this:

F(x) = x2 – 3x + 5 g(x) = V22 – 2x Calculate g (f (1)).

erik [133]

Step-by-step explanation:

So first of all we plug in 1 into f(x) and the result of that into g(x).

f(1)=(1)^2-3(1)+5

=1-3+5

g(3)=(3)(22)-2(3)

=66-6

=60
